【摘要】 Web服务是目前互联网的发展热点,正以其开放、简单、跨平台、低代价集成等优点引起相关研究人员和应用开发人员的重视。但是在传统的Web服务体系中,服务的发布和发现都是以一个服务注册中心为基础的,成为系统中潜在的瓶颈。如果服务注册中心失效则整个系统瘫痪。本文将P2P网络与Web服务有机结合,提出基于P2P网络的分布式Web服务模型,利用P2P的离散化技术提高网络的灵活性,并在SUN公司提供的P2P网络平台JXTA上予以实现。最后,通过对比实验对模型的性能进行验证,结果表明模型具有明显的自组织特性和良好的可扩展性,并具有较好的服务查找能力。更多还原

【Abstract】 Web Service is the new hotspot of present Internet development. Researchers and the application developers attach importance to its value of opening, simpleness, crossing platform and integration at low cost. But in traditional Web Service architecture, service publication and discovery are still based on a centralized server. UDDI is a bottle-neck in the architecture. If UDDI is disabled, the architecture will be failed. This thesis, which combines the P2P network and Web Service, presents a Web Service model based on P2P network, using the discretization of the P2P network to enhance the flexibility of Web Service. Main functions have been accomplished on JXTA platform provided by Sun. Finally, the comparison experiments show that, this model is scalable and well self-organized, with high service lacation quality.更多还原
